All Bettis actuators are shipped in the Left-Hand orientation unless ordered as Right-
Hand. The orientation may be reversed in the field by moving all accessories to the
opposite side of the shaft and turning the actuator top–side down.
Double-Acting (Left-Hand): pressure on the end cap ports pushes the pistons inward
and causes counterclockwise rotation. Pressure to the base plate ports pushes the
pistons outward resulting in a clockwise rotation.
Double-Acting (Right-Hand): pressure on the end cap ports pushes the pistons inward
and causes clockwise rotation. Pressure to the base plate ports pushes the pistons
outward resulting in a counterclockwise rotation.
